Description

spout bottle

[0001] This application claims priority to Chinese patent applications filed on July 9, 2024, with application number 2024109157098 entitled "Sip Bottle" and application number 2024216181190 entitled "Sip Bottle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of containers, specifically to a spout bottle. Background Technology

[0003] The speed at which milk flows from a baby bottle nipple depends on the size of the nipple's outlet, the baby's sucking strength, the volume of milk in the bottle, and the rate at which air enters the bottle. Currently, the outlet and air valve on baby bottle nipples are fixed. Although customers can choose different nipple sizes to change the flow rate, once the nipple is selected, the flow rate is fixed. For some babies with slow swallowing speeds, even using the smallest nipple outlet can sometimes result in the swallowing speed being slower than the flow rate, causing the baby to choke on milk. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a sippy bottle with an adjustable air intake rate, thereby allowing for adjustment of the liquid dispensing speed. When used as a baby bottle, it can better prevent infants from choking on milk.

[0005] This application provides a spout bottle, the spout bottle comprising:

[0006] Bottle assembly, the bottle assembly including a bottle body and a cap, the cap and the bottle body forming a receiving cavity, the cap including a spout; and

[0007] A ventilation mechanism, located within the accommodating cavity, is used to control the connection and closure of the accommodating cavity with the external environment. The ventilation mechanism includes a ventilation tube and an adjustment component. One end of the ventilation tube is connected to the bottle assembly and communicates with the outside of the bottle assembly. The other end of the ventilation tube is installed on the adjustment component. When the bottle assembly is under normal pressure, the adjustment component closes the ventilation tube. When the bottle assembly is under negative pressure, the adjustment component opens the ventilation tube. The adjustment component is also used to adjust the air intake rate of the ventilation tube when the bottle assembly is under negative pressure.

[0008] Furthermore, the venting tube has a first opening and a second opening. The first opening communicates with the outside of the bottle assembly, and the second opening communicates with the receiving cavity. The adjusting assembly includes a first adjusting member and a second adjusting member connected together. The first adjusting member is disposed at the second opening and is used to open or close the second opening. When the bottle assembly is under normal pressure, the first adjusting member abuts against the second opening of the venting tube to close the second opening. When the bottle assembly is under negative pressure, the first adjusting member is spaced apart from the second opening to connect the second opening with the receiving cavity. The second adjusting member is located on the side of the first adjusting member away from the second opening and is movably connected to the venting tube. The second adjusting member can move towards or away from the second opening relative to the venting tube. When the second adjusting member moves towards or away from the second opening and the bottle assembly is under negative pressure, the first adjusting member moves towards or away from the second opening, thereby adjusting the distance between the first adjusting member and the second opening, and thus adjusting the passage size between the venting tube and the receiving cavity to adjust the air intake rate of the venting mechanism.

[0009] Furthermore, the first adjusting member protrudes from one side of the second adjusting member. The vent pipe includes a connected air inlet pipe and a connecting pipe. The end of the air inlet pipe opposite to the connecting pipe has the first opening, and the end of the air inlet pipe connected to the connecting pipe has the second opening. The radial dimension of the connecting pipe is larger than the radial dimension of the air inlet pipe. The first adjusting member passes through the connecting pipe. The second adjusting member can rotate the end of the connecting pipe opposite to the air inlet pipe and is partially sleeved on the connecting pipe. The second adjusting member has a communicating hole that communicates with the accommodating cavity.

[0010] Furthermore, the first adjusting member is an elastic member. When the bottle assembly is under normal pressure, the first adjusting member is in a relaxed or compressed state. By adjusting the distance between the second adjusting member and the second opening, the compression degree of the first adjusting member is adjusted, thereby adjusting the distance between the first adjusting member and the second opening when the bottle assembly is under negative pressure, so as to change the air intake rate at the second opening.

[0011] Furthermore, the second adjusting member has a first position and a second position relative to the second opening. The first position is closer to the second opening than the second position. When the second adjusting member is in the first position, the first adjusting member is in a compressed state. When the second adjusting member is in the second position, the first adjusting member is in a compressed state or a relaxed state.

[0012] Furthermore, the first adjusting member includes a first elastic part and a second elastic part connected together. The radial dimension of the first elastic part is larger than the radial dimension of the second elastic part. When the bottle assembly is under normal pressure, the first elastic part abuts against the second opening, and the end of the second elastic part opposite to the first elastic part is connected to the second adjusting member.

[0013] Furthermore, the end of the connecting pipe opposite to the air intake pipe has an external thread; the second adjusting member has an adjusting part and a sleeve part that are bent and connected together, the adjusting part has the communicating hole, the sleeve part is arranged around the adjusting part, the sleeve part has an internal thread, and the external thread is threadedly connected to the internal thread.

[0014] Furthermore, the second elastic part has a through hole at one end opposite to the first elastic part, and the second adjusting member also includes a column part, the column part and the sleeve part are disposed on the same side of the adjusting part, and the column part is located inside the sleeve part, the column part passes through the through hole, and the column part is interference-fitted with the second elastic part.

[0015] Furthermore, the bottle assembly also includes a mounting component located between the bottle body and the cap body, and the mounting component is detachably connected to both the bottle body and the cap body.

[0016] Furthermore, one end of the vent tube facing away from the adjustment assembly passes through the bottle body or the cap body;

[0017] Alternatively, the ventilation mechanism may further include a ventilation disc, which is disposed at the end of the ventilation tube away from the adjustment component and located between the bottle body and the cap body, and the ventilation disc is used to connect the ventilation tube with the external environment.

[0018] The sippy bottle of this application embodiment includes a bottle assembly and a venting mechanism. The venting mechanism is located within the accommodating cavity and is used to control the communication and closure of the accommodating cavity with the external environment. The venting mechanism includes a venting tube and an adjusting component. One end of the venting tube is connected to the bottle assembly and communicates with the outside of the bottle assembly. The other end of the venting tube is installed on the adjusting component. When the bottle assembly is under normal pressure, the adjusting component closes the venting tube. When the bottle assembly is under negative pressure, the adjusting component opens the venting tube. The adjusting component is also used to adjust the air intake rate of the venting tube when the bottle assembly is under negative pressure. The adjusting component can not only control the opening and closing of the venting tube, but also adjust the air intake rate of the venting tube, thereby adjusting the flow rate of the fluid flowing out of the sippy bottle. This makes the sippy bottle more suitable for people of different ages. When used with infants, it can better prevent infants, especially those with slow swallowing speeds, from choking on milk or water. Attached Figure Description

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0035] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0036] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0037] It should be noted that, for ease of explanation, the same reference numerals denote the same components in the embodiments of this application, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0038] The speed at which milk flows from a baby bottle nipple depends on the size of the nipple's outlet, the baby's sucking strength, the volume of milk in the bottle, and the rate at which air enters the bottle. Currently, the outlet and air valve on baby bottle nipples are fixed. Although customers can choose different nipple sizes to change the flow rate, once the nipple is selected, the flow rate is fixed. For some babies with slow swallowing speeds, even using the smallest nipple outlet can sometimes result in the swallowing speed being slower than the flow rate, causing the baby to choke on milk.

[0039] Please refer to Figures 1 and 2. This application provides a spout bottle 100, which includes a bottle assembly 10 and a ventilation mechanism 20. The bottle assembly 10 includes a bottle body 11 and a cap 12, which together with the bottle body 11 form a receiving cavity 13. The cap 12 includes a spout 121. The ventilation mechanism 20 is located within the receiving cavity 13 and is used to control the connection and closure of the receiving cavity 13 with the external environment. The ventilation mechanism 20 includes a ventilation tube 21 and an adjustment component 2. 2. One end of the vent pipe 21 is connected to the bottle assembly 10 and communicates with the outside of the bottle assembly 10. The other end of the vent pipe 21 is installed on the regulating component 22. When the bottle assembly 10 is under normal pressure, the regulating component 22 closes the vent pipe 21. When the bottle assembly 10 is under negative pressure, the regulating component 22 opens the vent pipe 21. The regulating component 22 is also used to regulate the air intake rate of the vent pipe 21 when the bottle assembly 10 is under negative pressure.

[0040] The sippy bottle 100 in this application embodiment can be, but is not limited to, a baby bottle, a straw bottle, or other fluid container used to hold fluids such as water and milk. It should be noted that the sippy bottle 100 in the accompanying drawings of this application is illustrated using a baby bottle as an example, and should not be construed as a limitation on the sippy bottle 100 of this application. The sippy bottle 100 in this application embodiment can also be a fluid container of other shapes or forms.

[0041] Optionally, the nozzle 121 can be, but is not limited to, a nipple, a straw, etc.

[0042] Optionally, the bottle body 11 and the cap body 12 can be fixedly connected or detachably connected. Optionally, the venting component and the bottle assembly 10 can be separated, detachably connected, or fixedly connected.

[0043] It should be noted that the vent pipe 21 refers to a pipe with a channel, such as a pipe that allows gas or liquid to pass through.

[0044] Optionally, the suction nozzle 121 has a liquid outlet 1211. The suction nozzle 121 is used to draw fluid from the accommodating cavity 13.

[0045] It should be noted that when the bottle assembly 10 is under normal pressure, the regulating component 22 closes the vent pipe 21; when the suction bottle 100 stores fluid and draws it in, air is drawn in from the suction nozzle 121 to create a negative pressure inside the bottle assembly 10, so that the atmospheric pressure inside the bottle assembly 10 is lower than the external atmospheric pressure. Under the action of the external atmospheric pressure, the regulating component 22 opens the vent pipe 21, so that gas enters the accommodating cavity 13 from the outside (the gas flow direction is shown by the dotted arrow in Figure 1). In addition, the regulating component 22 can also adjust the air intake rate of the air inlet pipe, thereby adjusting the fluid flow rate of the suction nozzle 121.

[0046] The suction bottle 100 of this application embodiment includes a bottle assembly 10 and a ventilation mechanism 20. The ventilation mechanism 20 is located in the accommodating cavity 13 and is used to control the communication and closure of the accommodating cavity 13 with the external environment. The ventilation mechanism 20 includes a ventilation tube 21 and an adjustment component 22. One end of the ventilation tube 21 is connected to the bottle assembly 10 and communicates with the outside of the bottle assembly 10. The other end of the ventilation tube 21 is installed on the adjustment component 22. When the bottle assembly 10 is under normal pressure, the adjustment component 22 closes the ventilation tube 21. When the bottle assembly 10 is under negative pressure, the adjustment component 22 opens the ventilation tube 21. The adjustment component 22 is also used to adjust the air intake rate of the ventilation tube 21 when the bottle assembly 10 is under negative pressure. The adjustment component 22 can not only control the opening and closing of the ventilator 21, but also adjust the air intake rate of the ventilator 21, thereby adjusting the flow rate of the fluid flowing out of the mouthpiece 121. This makes the mouthpiece bottle 100 more suitable for people of different ages. When used for infants, it can better prevent infants, especially those with slow swallowing speed, from choking on milk or water.

[0047] Please refer to Figures 3 and 4. In some embodiments, the vent pipe 21 has a first opening 211 and a second opening 212. The first opening 211 communicates with the outside of the bottle assembly 10, and the second opening 212 communicates with the receiving cavity 13. The adjusting assembly 22 includes a first adjusting member 221 and a second adjusting member 222 connected together. The first adjusting member 221 is disposed at the second opening 212 and is used to open or close the second opening 212. When the bottle assembly 10 is under normal pressure, the first adjusting member 221 abuts against the second opening 212 of the vent pipe 21 to close the second opening 212. When the bottle assembly 10 is under negative pressure, the first adjusting member 221 and the second adjusting member 222... The openings 212 are spaced apart to connect the second opening 212 with the receiving cavity 13; the second adjusting member 222 is located on the side of the first adjusting member 221 away from the second opening 212 and is movably connected to the venting tube 21. The second adjusting member 222 can move towards or away from the second opening 212 relative to the venting tube 21. When the second adjusting member 222 moves towards or away from the second opening 212 and the bottle assembly 10 is under negative pressure, the first adjusting member 221 moves towards or away from the second opening 212, thereby adjusting the distance between the first adjusting member 221 and the second opening 212 to adjust the air intake rate of the venting mechanism 20.

[0048] Understandably, when the bottle assembly 10 is under negative pressure, the first adjusting member 221 moves away from the second opening 212, thereby maintaining a certain distance from the second opening 212 and opening the second opening 212 to allow gas to enter the receiving cavity 13 from the external environment. When the pressure inside the bottle assembly 10 returns to normal pressure, the first adjusting member 221 moves closer to the second opening 212, causing the first adjusting member 221 to press against the second opening 212 again, closing the second opening 212 once more.

[0049] Understandably, the second opening 212, the first adjusting member 221, and the second adjusting member 222 are arranged in sequence.

[0050] It should be noted that when the second adjusting member 222 moves towards the second opening 212, and the bottle assembly 10 is under negative pressure, the distance between the first adjusting member 221 and the second opening 212 decreases under the same negative pressure, thereby reducing the air intake rate of the second opening 212 and consequently reducing the fluid outflow rate of the nozzle 121. Conversely, when the second adjusting member 222 moves away from the second opening 212, and the bottle assembly 10 is under negative pressure, the distance between the first adjusting member 221 and the second opening 212 increases under the same negative pressure, thereby increasing the air intake rate of the second opening 212 and consequently increasing the fluid outflow rate of the nozzle 121. Therefore, by adjusting the relative distance between the second adjusting member 222 and the second opening 212, the distance between the first adjusting member 221 and the second opening 212 when the bottle assembly 10 is under negative pressure can be adjusted, thereby adjusting the air intake rate of the second opening 212 and ultimately changing the fluid outflow rate of the nozzle 121.

[0051] In this embodiment, by cooperating with the first adjusting member 221, the second adjusting member 222, and the vent tube 21, the relative distance between the second adjusting member 222 and the second opening 212 can be adjusted. This allows for adjustment of the distance between the first adjusting member 221 and the second opening 212 when the bottle assembly 10 is under negative pressure, thereby adjusting the opening or size of the second opening 212 and consequently adjusting the fluid outflow speed of the suction nozzle 121. In this way, when the fluid outflow speed of the suction nozzle 121 does not match the user's swallowing speed, it can be adjusted by the adjusting mechanism without the need to replace the suction nozzle 121 with a larger liquid outlet 1211, greatly improving the user experience.

[0052] Please refer to Figures 5 and 6. In some embodiments, the first adjusting member 221 protrudes from one side of the second adjusting member 222. The vent pipe 21 includes a connected air inlet pipe 213 and a connecting pipe 214. The end of the air inlet pipe 213 facing away from the connecting pipe 214 has the first opening 211, and the end of the air inlet pipe 213 connected to the connecting pipe 214 has the second opening 212. The radial dimension of the connecting pipe 214 is larger than the radial dimension of the air inlet pipe 213. The first adjusting member 221 passes through the connecting pipe 214. The second adjusting member 222 can rotate the end of the connecting pipe 214 facing away from the air inlet pipe 213 and is partially sleeved on the connecting pipe 214. The second adjusting member 222 has a communicating hole 2221 communicating with the accommodating cavity 13.

[0053] Understandably, the intake pipe 213 and the connecting pipe 214 have a channel-like tube body.

[0054] Optionally, the intake pipe 213 and the connecting pipe 214 can be an integral structure, and the intake pipe 213 and the connecting pipe 214 are different parts of the same component.

[0055] Optionally, the number of connecting holes 2221 can be one or more. When the number of connecting holes 2221 is multiple, the multiple connecting holes 2221 are arranged at intervals.

[0056] It should be noted that the inner diameter of the connecting pipe 214 is larger than the inner diameter of the air intake pipe 213, and the outer diameter of the connecting pipe 214 is also larger than the outer diameter of the air intake pipe 213.

[0057] Optionally, the connecting pipe 214 is connected to one end of the air intake pipe 213, and the size of the connecting pipe 214 gradually decreases.

[0058] It should be noted that when the bottle assembly 10 is under normal pressure, the first adjusting member 221 abuts against the connecting pipe 214 and closes the second opening 212. When the bottle assembly 10 is under negative pressure, the first adjusting member 221 has gaps with the second opening 212 and the connecting pipe 214.

[0059] It should be noted that when the bottle assembly 10 is under negative pressure, external gas enters from the first opening 211, passes through the second opening 212, the connecting pipe 214, and the connecting hole 2221 into the accommodating cavity 13.

[0060] Understandably, the connecting hole 2221 connects the accommodating cavity 13 and the connecting pipe 214.

[0061] In this embodiment, the radial dimension of the connecting pipe 214 is designed to be larger than that of the air inlet pipe 213, thereby forming a flared shape at the connection between the connecting pipe 214 and the air inlet pipe 213. The first adjusting member 221 is disposed inside the connecting pipe 214. This allows the first adjusting member 221 to better support the connecting pipe 214 and close the second opening 212 when the bottle assembly 10 is under normal pressure. When the bottle assembly 10 is under negative pressure, the second opening 212 has a more controllable opening. Through the limiting effect of the connecting pipe 214, the first adjusting member 221 is less likely to become misaligned during repeated inhalation, thus improving the service life of the ventilation mechanism 20.

[0062] In some embodiments, the first adjusting member 221 is an elastic member. When the bottle assembly 10 is under normal pressure, the first adjusting member 221 is in a relaxed state or a compressed state. By adjusting the distance between the second adjusting member 222 and the second opening 212, the compression degree of the first adjusting member 221 is adjusted, thereby adjusting the distance between the first adjusting member 221 and the second opening 212 when the bottle assembly 10 is under negative pressure, so as to change the air intake rate at the second opening 212.

[0063] It should be noted that when the suction nozzle 121 draws air, a negative pressure is generated inside the bottle assembly 10, making the atmospheric pressure inside the bottle assembly 10 lower than the external atmospheric pressure. Under the action of the external atmospheric pressure, the first adjusting member 221 is compressed, creating a gap between the first adjusting member 221 and the second opening 212, thereby allowing gas to enter the receiving cavity 13. When the second adjusting member 222 moves towards the second opening 212, the degree of compression of the first adjusting member 221 increases, resulting in a greater rebound force. If air is drawn through the suction nozzle 121 again at this time, with the suction force remaining unchanged, the compression of the first adjusting member 221 by the external atmospheric pressure will decrease due to the greater rebound force of the first adjusting member 221. This reduces the distance between the first adjusting member 221 and the second opening 212, thereby reducing the air intake rate at the second opening 212 and adjusting the liquid discharge speed of the suction nozzle 121.

[0064] Understandably, the first adjusting member 221 is elastic and will undergo elastic deformation under the action of external force. After the external force disappears, the first adjusting member 221 will deform and recover to its initial state.

[0065] It should be noted that the relaxed state refers to a state that is neither stretched nor compressed, that is, a balanced state that is not subject to external forces.

[0066] In this embodiment, by adjusting the distance between the second adjusting member 222 and the second opening 212, the compression degree of the first adjusting member 221 is adjusted, thereby adjusting the distance the first adjusting member 221 moves away from the second opening 212 when the bottle assembly 10 is in a negative pressure state, thus adjusting the air intake rate of the second opening 212, and consequently adjusting the liquid discharge speed of the liquid outlet 1211 of the nozzle 121. This makes the nozzle bottle 100 more suitable for people of different ages. When used with infants, it can better prevent infants, especially those with slower swallowing speeds, from choking on milk or water. When the fluid flow rate of the nozzle 121 does not match the user's swallowing speed, the liquid discharge speed of the liquid outlet 1211 can be adjusted by adjusting the distance between the second adjusting member 222 and the second opening 212, without needing to replace the nozzle 121 with one having a larger liquid outlet 1211, greatly improving the user experience.

[0067] The suction bottle 100 of this application embodiment includes a bottle assembly 10 and a ventilation mechanism 20. The ventilation mechanism 20 is located in the accommodating cavity 13 and is used to control the communication and closure of the accommodating cavity 13 with the external environment. The ventilation mechanism 20 includes a ventilation tube 21 and an adjustment component 22. One end of the ventilation tube 21 is connected to the bottle assembly 10 and communicates with the outside of the bottle assembly 10. The other end of the ventilation tube 21 is installed on the adjustment component 22. When the bottle assembly 10 is under normal pressure, the adjustment component 22 closes the ventilation tube 21. When the bottle assembly 10 is under negative pressure, the adjustment component 22 opens the ventilation tube 21. The adjustment component 22 is also used to adjust the air intake rate of the ventilation tube 21 when the bottle assembly 10 is under negative pressure. The adjustment component 22 can not only control the opening and closing of the ventilator 21, but also adjust the air intake rate of the ventilator 21, thereby adjusting the flow rate of the fluid flowing out of the mouthpiece 121. This makes the mouthpiece bottle 100 more suitable for people of different ages. When used for infants, it can better prevent infants, especially those with slow swallowing speed, from choking on milk or water.

[0068] Please refer to Figures 7 and 8. In some embodiments, the second adjusting member 222 has a first position (as shown in Figure 7) and a second position (as shown in Figure 8) relative to the second opening 212. The first position is closer to the second opening 212 than the second position. When the second adjusting member 222 is in the first position, the first adjusting member 221 is in a compressed state. When the second adjusting member 222 is in the second position, the first adjusting member 221 is in a compressed state or a relaxed state.

[0069] Understandably, the second adjusting member 222 can move relative to the second opening 212 between a first position and a second position.

[0070] It should be noted that the first adjusting member 221 can only be in a relaxed state when the second adjusting member 222 is in the second position. However, preferably, the first adjusting member 221 is in a compressed state when the second adjusting member 222 is in the second position. When the second adjusting member 222 is in the second position and the first adjusting member 221 is in a compressed state, this ensures that even when the bottle assembly 10 is under normal pressure, the first adjusting member 221 also has a certain elastic restoring force, which can better resist and seal the second opening 212, thereby better ensuring the airtightness of the spout bottle 100.

[0071] It should be noted that when the second adjusting member 222 is between the first position and the second position, the first adjusting member 221 is in a compressed state. The closer the second adjusting member 222 is to the first position, the higher the degree of compression of the first adjusting member 221.

[0072] In this embodiment, when the second adjusting member 222 is in the first position, the first adjusting member 221 is in a compressed state; when the second adjusting member 222 is in the second position, the first adjusting member 221 is in a compressed or relaxed state. This ensures that when the bottle assembly 10 is under normal pressure, the first adjusting member 221 always closes the second opening 212, making it less likely for liquid to leak from the vent tube 21; the second opening 212 only opens when liquid is drawn from the suction nozzle 121.

[0073] Please refer to Figure 9. In some embodiments, the first adjusting member 221 includes a first elastic part 2211 and a second elastic part 2212 connected together. The radial dimension of the first elastic part 2211 is larger than the radial dimension of the second elastic part 2212. When the bottle assembly 10 is under normal pressure, the first elastic part 2211 abuts against the second opening 212, and the end of the second elastic part 2212 opposite to the first elastic part 2211 is connected to the second adjusting member 222.

[0074] Optionally, the inner wall of the connecting pipe 214 near the second opening 212 is an arc surface, and the surface of the first elastic part 2211 facing the second opening 212 is an arc surface. In a specific embodiment, the inner wall of the connecting pipe 214 near the second opening 212 is a spherical surface, and the surface of the first elastic part 2211 facing the second opening 212 is a spherical surface.

[0075] Optionally, the radial dimension of the first elastic portion 2211 is larger than the radial dimension of the second opening 212, so that when the first elastic portion 2211 abuts against the second opening 212, the first elastic portion 2211 can better close the second opening 212.

[0076] Optionally, the first elastic part 2211 and the second elastic part 2212 can be an integral structure; or they can be separate structures, manufactured separately and then assembled together.

[0077] Understandably, when the nozzle 121 draws in air, a negative pressure is generated inside the bottle assembly 10, which makes the atmospheric pressure inside the bottle assembly 10 lower than the external atmospheric pressure. Under the action of the external atmospheric pressure, the first elastic part 2211 and the second elastic part 2212 are compressed, creating a gap between the first elastic part 2211 and the second opening 212, thereby allowing gas to enter the accommodating cavity 13. When the second adjusting member 222 moves toward the direction closer to the second opening 212, the degree of compression of the first elastic part 2211 and the second elastic part 2212 increases, resulting in a greater rebound force. If air is drawn in again through the suction nozzle 121 at this time, with the suction force remaining unchanged, the compression of the first elastic part 2211 and the second elastic part 2212 by the external atmospheric pressure will decrease because the first elastic part 2211 and the second elastic part 2212 have a greater rebound force. This reduces the distance between the first elastic part 2211 and the second opening 212, thereby reducing the air intake rate at the second opening 212 and adjusting the liquid discharge speed of the suction nozzle 121.

[0078] Optionally, the material of the first elastic part 2211 may be, but is not limited to, silicone. Optionally, the shape of the first elastic part 2211 may be hemispherical, and the first elastic part 2211 may be solid or hollow.

[0079] Optionally, the material of the second elastic part 2212 may be, but is not limited to, silicone. Optionally, the second elastic part 2212 may be, but is not limited to, an elastic column, a spring, etc.

[0080] Optionally, the elastic modulus of the first elastic part 2211 is smaller than that of the second elastic part 2212. This allows the second elastic part 2212 to provide better support for the first elastic part 2211. When the bottle assembly 10 is under normal pressure, the second elastic part 2212 can better support the first elastic part 2211, so that the first elastic part 2211 tightly abuts against the second opening 212 and better seals the second opening 212.

[0081] Optionally, the average density of the first elastic part 2211 is less than the density of water. In this way, when water or milk is contained in the accommodating cavity 13, the buoyancy force on the first elastic part 2211 is greater than the weight of the first elastic part 2211, thereby allowing the first elastic part 2211 to better resist the second opening 212 due to the buoyancy force and seal the second opening 212.

[0082] In this embodiment, the first adjusting member 221 includes a first elastic portion 2211 and a second elastic portion 2212 connected together. The radial dimension of the first elastic portion 2211 is larger than the radial dimension of the second elastic portion 2212. This allows the first elastic portion 2211 to better seal the second opening 212 when it abuts against it. Simultaneously, through the cooperation of the first elastic portion 2211 and the second elastic portion 2212, when the bottle-splitting assembly 10 is under negative pressure, the distance between the first elastic portion 2211 and the second opening 212 has a larger adjustment range, thereby allowing for greater adjustment of the flow rate of the liquid exiting the nozzle 121.

[0083] Please refer again to Figures 7 and 8. In some embodiments, the end of the connecting pipe 214 facing away from the air intake pipe 213 has an external thread; the second adjusting member 222 is bent and connected to the adjusting part 2222 and the sleeve part 2223. The adjusting part 2222 has the communicating hole 2221. The sleeve part 2223 is arranged around the adjusting part 2222. The sleeve part 2223 has an internal thread. The external thread is threadedly connected to the internal thread.

[0084] Optionally, corresponding scales or numbers can be provided on the outer surface of the connecting tube 214 or the sleeve 2223 to facilitate user identification and adjustment. For example, one of the connecting tube 214 and the sleeve 2223 may have an arrow, and the other may have a number. The arrow pointing to the corresponding number indicates the position suitable for an infant of the corresponding age or month.

[0085] In one specific embodiment, when the second adjusting member 222 is fully tightened (at which point the distance between the second adjusting member 222 and the second opening 212 is at its minimum, and the compression degree of the first adjusting member 221 is at its maximum), mark 0 at the position corresponding to the connecting tube 214 or the sleeve 2223, and mark values ​​1, 2, 3, 4, etc. sequentially along the direction in which the second adjusting member 222 is loosened. This allows the user to quickly adjust the scale to match the infant's age, ensuring a suitable fluid flow rate at the nozzle 121. If the air intake rate is too low, simply loosen the second adjusting member 222 slightly; if the air intake rate is too high, simply tighten the second adjusting member 222 slightly.

[0086] In this embodiment, the threaded connection between the external thread of the connecting pipe 214 and the internal thread of the sleeve 2223 facilitates the installation of the second adjusting member 222. Furthermore, by simply tightening or loosening the second adjusting member 222, the distance between the second adjusting member 222 and the second opening 212 can be adjusted, thereby adjusting the degree of compression of the first adjusting member 221. This, in turn, adjusts the gap between the first adjusting member 221 and the second opening 212 when the bottle assembly 10 is under negative pressure, thereby adjusting the air intake rate at the second opening 212. Thus, the flow rate of the fluid flowing out of the nozzle 121 is adjusted.

[0087] Please refer to Figure 10. In some embodiments, the vent pipe 21 further includes a first limiting member 215, which is disposed at one end of the external thread of the connecting pipe 214 near the air inlet pipe 213, and is used to limit the first position of the second adjusting member 222.

[0088] In this embodiment, by setting a first limiting member 215 at the end of the external thread closer to the air inlet pipe 213, the second adjusting member 222 is limited, preventing the user from continuing to tighten the second adjusting member 222 after it has been screwed to the first position, causing the second adjusting member 222 to be over-tightened. This results in the second adjusting member 222 and the second opening 212 being too close, so that when the bottle assembly 10 is under negative pressure, the first adjusting member 221 still abuts against the second opening 212, affecting the air intake of the second opening 212 and thus affecting the use of the spout bottle 100.

[0089] In some embodiments, the vent pipe 21 further includes a second limiting member 216, which is disposed at the end of the external thread of the connecting pipe 214 away from the air inlet pipe 213, and is used to limit the second position of the second adjusting member 222.

[0090] In this embodiment, by setting a second limiting member 216 at the end of the external thread further away from the air inlet pipe 213, the second adjusting member 222 is limited, preventing the user from continuing to loosen the second adjusting member 222 after it has been screwed to the second position, causing the second adjusting member 222 to be over-tightened. This would result in an excessively large gap between the second adjusting member 222 and the second opening 212. When the bottle assembly 10 is under normal pressure, there will be a gap between the first adjusting member 221 and the second opening 212, causing the liquid inside the bottle assembly 10 to leak out from the venting mechanism 20, affecting the user experience.

[0091] Please refer again to Figure 9. In some embodiments, the second elastic part 2212 has a through hole 2213 at one end opposite to the first elastic part 2211. The second adjusting member 222 also includes a column part 2224. The column part 2224 and the sleeve part 2223 are disposed on the same side of the adjusting part 2222, and the column part 2224 is located inside the sleeve part 2223. The column part 2224 passes through the through hole 2213, and the column part 2224 is interference-fitted with the second elastic part 2212.

[0092] Understandably, the sleeve portion 2223 is disposed around the outer periphery of the column portion 2224 and spaced apart from the column portion 2224, and the connecting hole 2221 is located between the sleeve portion 2223 and the column portion 2224; in other words, the connecting hole 2221 of the adjusting portion 2222 is offset from the sleeve portion 2223 and offset from the column portion 2224.

[0093] Understandably, the second elastic part 2212 is fitted around the outer periphery of the column part 2224.

[0094] In this embodiment, by providing a through hole 2213 on the second elastic part 2212 and a column part 2224 on the second adjusting member 222, the second elastic part 2212 is fitted onto the outer periphery of the column part 2224. This facilitates the assembly of the first adjusting member 221 and the second adjusting member 222, simplifies the assembly process of the ventilation mechanism 20, and reduces the cost of the ventilation mechanism 20. Furthermore, this also facilitates the disassembly and cleaning of the ventilation mechanism 20.

[0095] Please refer to Figures 2 and 11 together. In some embodiments, the bottle assembly 10 further includes a mounting member 14 located between the bottle body 11 and the cap 12. The mounting member 14 is detachably connected to the bottle body 11 and the cap 12 respectively.

[0096] Optionally, the cap 12 and the mounting member 14 are detachably connected by a snap fastener, and the mounting member 14 and the bottle body 11 are detachably connected by a threaded connection.

[0097] In this embodiment, a mounting component 14 is provided, which is detachably connected to both the bottle body 11 and the cap body 12. This facilitates the assembly of the bottle assembly 10 and also makes it easier to disassemble and clean the bottle assembly 10.

[0098] In some embodiments, the cover 12 further includes a cover body 122, which surrounds the outer periphery of the suction nozzle 121 such that the suction nozzle 121 protrudes from the side of the cover body 122 opposite to the mounting member 14. The end of the cover body 122 near the mounting member 14 has a first groove 1221 and a second groove 1222. Both the first groove 1221 and the second groove 1222 are located on the outer side wall of the cover body 122. The first groove 1221 and the second groove 1222 communicate with each other and are bent towards each other. The mounting component 14 includes a mounting portion 141, a first protrusion 142, and a second protrusion 143. The mounting portion 141 has an annular structure and an internal thread. The first protrusion 142 protrudes from the surface of the mounting portion 141 facing the cap body 122. The second protrusion 143 is located between the internal thread of the mounting portion 141 and the first protrusion 142, and protrudes from the inner wall of the mounting portion 141. The first protrusion 142 and the second protrusion 143 are bent and connected vertically. The first protrusion 142 engages with the first groove 1221, and the second protrusion 143 engages with the second groove 1222. The bottle body 11 has an external thread on the side near the mounting component 14, and the internal thread of the mounting component 14 and the external thread of the bottle body 11 are threadedly connected.

[0099] In this embodiment, the snap-fit ​​engagement of the first protrusion 142 with the first groove 1221 and the second protrusion 143 with the second groove 1222 allows for a better connection between the cap body 122 and the mounting member 14, thereby better preventing leakage. Furthermore, the snap-fit ​​engagement of the first protrusion 142 with the first groove 1221 and the second protrusion 143 with the second groove 1222 also makes the cap body 122 and the mounting member 14 detachable, facilitating the disassembly and cleaning of the bottle assembly 10.

[0100] Please refer to Figures 11 to 13. In some embodiments, the end of the vent pipe 21 facing away from the adjustment component 22 passes through the bottle body 11 or the cap 12; or, the venting mechanism 20 further includes a venting disc, which is disposed at the end of the vent pipe 21 facing away from the adjustment component 22 and located between the bottle body 11 and the cap 12. The venting disc is used to connect the vent pipe 21 with the external environment.

[0101] Please refer to Figure 11. In some embodiments, one end of the vent pipe 21 that is away from the adjustment component 22 passes through the cover body 122 of the cover 12 and is interference-fitted with the cover body 122.

[0102] Please refer to Figure 12. In some other embodiments, the end of the vent tube 21 facing away from the adjustment component 22 passes through the bottle body 11 (e.g., the bottom of the bottle body 11) and is interference-fitted with the bottle body 11.

[0103] Please refer to Figure 13. In some other embodiments, the ventilation mechanism 20 further includes a ventilation disc 23, which is disposed at the end of the ventilation pipe 21 away from the adjustment component 22 and located between the bottle body 11 and the cap body 12. The ventilation disc 23 is used to connect the ventilation pipe 21 with the external environment.

[0104] Understandably, the vent plate 23 is connected to the outside and the vent pipe 21 is connected to the vent plate 23.

[0105] Optionally, the ventilation plate 23 is a Helen plate, on which a ventilation channel 231 is provided.

[0106] Optionally, when the ventilation mechanism 20 further includes a ventilation disc 23, an air inlet is provided between the mounting component 14 and the bottle body 11. The air inlet is connected to the ventilation channel 231 of the Helen disc, thereby allowing the ventilation pipe 21 to connect to the external environment.

[0107] In this embodiment, the end of the vent pipe 21 facing away from the adjustment component 22 has multiple design options, which can better meet the different needs of different users.
